Abstract (en)
[origin: CN112304381A] The invention relates to an overpressure packaging device, comprising: a housing (2), which is connected to a purge gas source (5) via a purge gas inlet (3); an inlet valve (6) arranged between the purge gas source (5) and the purge gas inlet (3); a pressure gauge or pressure monitor (10) for monitoring the internal pressure in the housing (2); a control device (11), which is designed to control the inlet valve (6) in order to maintain a desired pressure in the housing (2); the flow meter (7) is used for detecting the inflow amount of the purge gas and is positioned between the purge gas source (5) and the purge gas inlet (3); and an evaluation device (13) which pre-calculates a trend curve of the purge gas inflow amount and a point in time when the trend curve exceeds a threshold value.
